Question 360
A public connection reaches a firewall frontend IP but never arrives at the internal endpoint because DNAT translation is missing. A review identifies this consequence: An allow rule without the needed translation does not deliver traffic to the private target. What is the BEST controlled recovery once this failure is recognized?
- The controlled remediation is to use a storage SAS token to translate firewall packet destinations.
- The controlled remediation is to correct the DNAT mapping and validate only the intended published service.
- The controlled remediation is to open all private subnet ports to the Internet instead of configuring DNAT.
- The controlled remediation is to assume an outbound application rule automatically publishes an inbound service.
Explanation
Correct Answer
B:Test using these records: Public IP, DNAT rule mapping, destination reachability and firewall flow log. Azure Firewall destination NAT performs explicit inbound address and port translation.
Incorrect Answers
A:Use a storage SAS token to translate firewall packet destinations. This would not reliably restore the intended security boundary. An allow rule without the needed translation does not deliver traffic to the private target. The appropriate controlled recovery is: Correct the DNAT mapping and validate only the intended published service.
C:Open all private subnet ports to the Internet instead of configuring DNAT. This would not reliably restore the intended security boundary. An allow rule without the needed translation does not deliver traffic to the private target. The appropriate controlled recovery is: Correct the DNAT mapping and validate only the intended published service.
D:Assume an outbound application rule automatically publishes an inbound service. This would not reliably restore the intended security boundary. An allow rule without the needed translation does not deliver traffic to the private target. The appropriate controlled recovery is: Correct the DNAT mapping and validate only the intended published service.
Question 361
Two regional Azure Firewall instances drift in threat intelligence and egress policy because each is configured separately. What is the BEST supported implementation or corrective action?
- Edit individual firewall instances without recording common policy changes.
- Replace all managed firewalls with NSG rules and call it equivalent inspection.
- Assume one custom DNS record centrally manages every firewall security rule.
- Use Azure Firewall Manager and shared Firewall Policy objects for centrally governed rule configuration.
Explanation
Correct Answer
D:Confirm the change against these records: Firewall Manager deployment, associated Firewall Policies, inherited rules and regional log evidence. Central policy management helps apply consistent Azure Firewall controls across supported deployments.
Incorrect Answers
A:Unmanaged independent rule changes can create contradictory security behavior across regions. Edit individual firewall instances without recording common policy changes.
B:Replace all managed firewalls with NSG rules and call it equivalent inspection. The proposed change targets the wrong mechanism or lacks essential validation. Central policy management helps apply consistent Azure Firewall controls across supported deployments. Relevant evidence is firewall Manager deployment, associated Firewall Policies, inherited rules and regional log evidence.
C:Unmanaged independent rule changes can create contradictory security behavior across regions. The intended action is: Use Azure Firewall Manager and shared Firewall Policy objects for centrally governed rule configuration.
Question 362
Two regional Azure Firewall instances drift in threat intelligence and egress policy because each is configured separately. Which evidence BEST verifies the intended technical behavior?
- A successful connection to a different address and different service port.
- The name of a firewall policy without its applied match and request logs.
- A static virtual network diagram with no effective route or packet observation.
- Firewall Manager deployment, associated Firewall Policies, inherited rules and regional log evidence.
Explanation
Correct Answer
D:These records test the actual Azure Firewall Manager central policy behavior rather than an unrelated dashboard state. Central policy management helps apply consistent Azure Firewall controls across supported deployments.
Incorrect Answers
A:On its own, that evidence does not prove the specified security control works. Central policy management helps apply consistent Azure Firewall controls across supported deployments.
B:On its own, that evidence does not prove the specified security control works. The more relevant observations are: Firewall Manager deployment, associated Firewall Policies, inherited rules and regional log evidence.
C:On its own, that evidence does not prove the specified security control works. In the given case, two regional Azure Firewall instances drift in threat intelligence and egress policy because each is configured separately.
Question 363
Two regional Azure Firewall instances drift in threat intelligence and egress policy because each is configured separately. Which principle BEST explains why the recommended solution is appropriate?
- A network appliance presence guarantees the effective route traverses it.
- Central policy management helps apply consistent Azure Firewall controls across supported deployments.
- Creating a virtual network peering link makes all other Azure VNets transitively reachable.
- An HTTP load balancer automatically inspects every malicious request as a WAF.
Explanation
Correct Answer
B:Confirmation depends on Firewall Manager deployment, associated Firewall Policies, inherited rules and regional log evidence. This principle supports the security response: Use Azure Firewall Manager and shared Firewall Policy objects for centrally governed rule configuration.
Incorrect Answers
A:A network appliance presence guarantees the effective route traverses it. This is an incorrect assumption for Azure Firewall Manager central policy. The relevant security behavior is: Central policy management helps apply consistent Azure Firewall controls across supported deployments. Check evidence such as firewall Manager deployment, associated Firewall Policies, inherited rules and regional log evidence.

Question 364
Two regional Azure Firewall instances drift in threat intelligence and egress policy because each is configured separately. Suppose the operator instead follows this unsafe shortcut: Edit individual firewall instances without recording common policy changes. What is the MOST significant failure introduced by that shortcut?
- A VNet diagram label alone explains the blocked or uninspected traffic.
- Changing a resource description fixes every underlying transport rule.
- Unmanaged independent rule changes can create contradictory security behavior across regions.
- The root problem was using a permitted endpoint reachability test.
Explanation
Correct Answer
C:The suitable control is: Use Azure Firewall Manager and shared Firewall Policy objects for centrally governed rule configuration. Central policy management helps apply consistent Azure Firewall controls across supported deployments.
Incorrect Answers
A:This does not explain the real Azure Firewall Manager central policy weakness after the shortcut. The material failure is: Unmanaged independent rule changes can create contradictory security behavior across regions.
B:This does not explain the real Azure Firewall Manager central policy weakness after the shortcut. Inspect evidence such as firewall Manager deployment, associated Firewall Policies, inherited rules and regional log evidence.
D:This does not explain the real Azure Firewall Manager central policy weakness after the shortcut. In the given case, two regional Azure Firewall instances drift in threat intelligence and egress policy because each is configured separately.
Question 365

Question 369
An organization needs consistent firewall governance across several secured virtual hubs and virtual networks. Suppose the operator instead follows this unsafe shortcut: Edit individual firewall instances without recording common policy changes. Which resulting risk or fault should the reviewer identify?
